Taking large amounts of money out of my account without notice, although all my payments are up to date

<p>I recieved an sms from vodacom that my payment of R15 734.32 does not reflect and that I need to make payment urgently. I immediately phoned in as I know that I have no payment outstanding. After arguing with me for 10 minutes the lady who assisted me checked my account and saw that I had no payments outstanding and that everything was up to date, that vodacom made an error. She then told me that vodacom already put the debit order through to the bank, and that I had to stop it myself at the bank. I asked her what the reason was that vodacom would deduct R15 734.32 from my bank account, and she told me she did not know, but would escalate the matter to her supervisor. I was promised that the supervisor would phone me back, however that never happened. I would like to know from vodacom: 1. what error was made in order for them to decide to deduct R15 734.32 ********ly from my account 2. Why was I not contacted before the debit order was sent through to the bank? Surely if there are monies outstanding someone is supposed to phone or send an email or sms asking when payment would take place before money is just deducted from my account 3. Why did I not recieve a call from the supervisor as promised giving me the answers to the above two questions 4. What will be done to ensure this error is not made again 5. Will vodacom be responsible for the bank charges that I have occured due to their error</p>
